Mirei is a divorced single mother. She had been in a relationship with a younger man who was a regular at her workplace, nurturing their love for each other. However, her son opposed her relationship with the younger man. Mirei struggled but ended up marrying an older man she met through some circumstances, who also had a child from a previous marriage. During the meeting with her husband's son, when Mirei said 'Nice to meet you,' the younger man was sitting right in front of her. Yes, Mirei wanted to live with him no matter what, so she married his father. Her wish came true, and the four of them started living together. One night, after her husband had fallen asleep, Mirei was embraced by him for the first time in a long while. Unable to make a sound, they quietly entwined their bodies, confirming their love for each other. Days passed, but Mirei couldn't make love with him. Being so close yet unable to touch each other drove Mirei mad. Just then, her husband and son suggested going out drinking together to strengthen their father-son bond. Towards the two who knew nothing, Mirei felt a pang of guilt, her chest tightening, but just imagining being embraced by him without any reservations made her lower half burn with heat, shameful stains spreading across her underwear...
